SELF-PBOPELLED VEHICLE.

Application filed 4 m 28,

Be it known that I, O'1'r0 ARMLEDEB, a citizen of the United States, residing at Wyoming, in the county offlI-Iamilton and State of Ohio, have invented certain new and useful Improvements in Self-Propelled Vehicles, of which-the following is a specifi cation.

I In self-propelled vehicles, including trucks,

tual relative movements between its parts usually take place. For instance, there may vbe a torsional movement in the structure,

occasioned by 'one wheel striking a boulder or being let into a rut, whereby one corner of the. chassis is subjected to severe strains,

which result in movement of that corner up ages of the motor-frame or partsor down with relation to the balance ofthe' chassis. The chassis is also frequently subjected to longitudinal strains in reverse directions at its respective sides, producing hinge-like strains on and movements at the corners of the chassis and movements in reverse directions of the sides. Other strains and movements are also caused. These strains and vibrations are rapidly recurrent.

ments in thechassis arecommunicated directly to the motor, resulting in detrimental strains inthe motor and frequently in break- It is the object of m invention to avoid .these objections, and, urthermore, to provide supporting means for a motor on the chassis arranged to compensate for the strains and movements to which the chassis is subjected; further, to provide acomparativel'y stifl bent leaf-spring having its edges presented up and down, between the chassis and the motor-frame, preferably at each side of one end of the motor-frame; further, to providesuch suspension in connec-: tion with a pivot-suspension at the other end of the motor frame; and, further, to

provide novel means whereby a resiliently Specification of Letters Patent. Patented Aug. 31,

7 strains and movements in the chassis, so as to prevent injury to or breakage of the motor or motor-frame or parts. 7

Theinvention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure l is a pl an view of my improved device, as applied to a motor truck, the chassis being partly broken away and partly in section.

Fig. 2 is a side elevation of the same.

Fig. 3 is a front end view of my improved device, the motor-frame being partlybroken away, and the chassis shown in section on the line 3 -3 of Fig. 1.

Fig. 4 is a plan view detail of the same, the chassis being shown in section on' the line 44 of'Fig. '3.

Fig. 5 is a detail of the same in vertical section, taken on the line 5--5 of Fig. 3.

Fig. 6 is a rear end view of my improved device, the chassis being shown in section on the line 6-6 of Fig. 1.

Fig. 7- is a perspective view of one of the spring supports.

Fig. 8 is a plan view detail, partly in sec tion, showing .theconnection of the spring su port with the motor and the chassis.

1g. 9 1s a vertical section of the same,

"taken on the line 99 of Fig. 8; and,

Fig. 10 is a vertical=section of the same, taken onthe line 10-10 of Fig. -8.

The chassis is represented at 11, and in I the present exemplification comprises. .side I-beams 12 and end cross-girts 13, 14, suitably bolted or riveted together at the corners, for forming as-rigid a structure as possible. The chassis may, if desired, be

provided with suitable cross-braces or diagonal braces as is usual in constructions of this nature.

The motor is exemplified at 18,- and may be a motor of any suitable .construction, being shown as an internal comhg'sti'on .motor, having its crank-shaft 19 extending lengthwise of the chassis.

The mounting of the motor on the chassis is shown as a three-point suspension mounting, comprising apivotal mounting at one. end of the motor and a resilient mountingv at each side of'the other end of the motor.

T has one end of the motor, represented as the front end, is hung from a pivot-stud 21 received in "bearings 22 of lugs 23 extending from the motor frame. The pivot is located intermediate of the sides of the motor-frame. The pivot is also received through a bearing 24 ina cross-beam 25.- This cross-beam has bearings 26 at its respective ends. A plvotbolt 27 is received through the bearing 26 at each end of the cross-beam and a bearing 28 in a bracket 29, one of thesebrackets being located at each end of the cross-beam, the brackets at the respective sides of the chassis being secured to the side beams thereof, as by bolts 30 and nuts 31. A nut 32 also coacts with each of the bolts 27 for firmly holding but resiliently yieldable to accommodate undue strains and movements in the chassis in order to avoid damage and breakage which might be due to unyielding connections between the same, such unyielding connections .having heretofore resulted in damage and breakage to the motor and its parts.

The leaf-springs are referably of heavy vanadium spring steel. hey are preferably bent in form with their edges presented up and down. They are shown of substantially U-shape, comprising limbs 37 and 38. The open ends of the bent leaf-springs are preferably presented in the direction of length of the chassis. The limbs 37 are shown secured to the side I-beams 12 at the respective sides of the chassis, the limbs 38 being secured to the motor-frame.

The limbs 37 are preferably secured in rigid manner to the chassis. Thus a bolt 39 passes through a hole 40 in the spring and a hole 41 in the I-beam, a nut 42 clamping the parts in place, and a bolt 43 passes through a slot 44 in the limb 37 and a hole 45in the chassis, a nut 46 clamping the parts 1 n place. The slot is provided to permit adjustment of the spring with relation to the chassis and the motor-frame, using the bolt 39 asa pivot during adjustment so as to provide relative adjusting means between the motor'and the chassis when mounting the motor in the chassis.

- A bolt 51 is received throu h a hole 52 in the limb 37, and a hole 53 in t e limb 38, and is threaded into a threaded hole 54 in the motor-frame, the hole 52 being provided merely for the purpose of permitting the.

headed bolt, which is a substantially dong bolt, to be received in the hole 53 and into the motor-frame. The construction contemplates theattachment of the springs to the motor-frame priorto theattachment of the same to the chassis.

The motor is provided with a rib 56 at 7 each side thereof, above the respective'limbs 38 of thespring, each of the ribs, however, being spaced from the limb 38 by a space .57. The ribs are preferably not intended to act as normal supports for the motor on the springs, but merely as safety members to prevent dropping of the motor in casethe.

bolts 51, or either of the same, which secure the springs to the motor-frame, should break, shear off, or become loose. The mountings of the motor-frame on the springs are preferably pivotal mountings, pivotal yield at the respective sides of that end of the motor-frame being permitted relatively to the chassis on the respective bolts 51.

The motor is supported firmly for all power transmission purposes. In case there should be torsional movement 0? caused, for instance, by the-rais ng or dropping of one corner, relative movefiient between the chassis and the motor-frame is permitted by the resilient yieldable subthe chassis,

stantially stiffsupporting springs 36. The

pivotal connections at the forward end of the motor, in the present exemplification, also compensate'for sl ch resiliently yielding movements. In case of opposite-lengthwise strains or movements at the respective I sides of the chassis, the spring-supports 36 are permitted to compensate for such strains or movements by yielding in the springs, the pivotal connections of the cross-beam 25 with the chassis and the motor-frame aiding in compensating for such strains and movements. f

The spring mountings permit resilient yielding in thedirection of length of the chassis and in directions perpendicular to ings of the motor-frame being complemental to and aiding in such movements.

'While I have shown the spring-supports ;at only one end of the motor, and have shown one at each side of said end, it is obvious that the number of spring-supports may be changed, and that other changes in construction may bemade, without departing from my invention within the scope of the append- .ed claims. i g
